Suggestions For An Appraiser

Give the situation you describe, you don't want an appraisal. An appraisal would give you what it would cost you to replace your collection, or what it might sell for at the retail level or at auction. Any dealer you go to will offer you much less than that, since they need to stay in business.
Since it seems that you want to know the proceeds you would receive from a potential sale, perhaps the easiest (certainly least costly) choice might just be to search ebay for "sold" examples of each of your coins. The only issue of course, is to find examples in the condition to whatever you have so you get accurate numbers.
